Product Description

Releco C3-A38 BX 24V is a premium PCB mount power relay designed for reliable switching in demanding industrial and automation environments. It operates with a 24V AC/DC coil and provides a robust switching current capacity of 10A, suitable for various control systems.

The relay’s 3PDT (three-pole double-throw) contact configuration allows it to control multiple circuits simultaneously, making it versatile for complex applications. A dual function test button - colour-coded for ease - is included, enabling operators to push to test or lift to latch the relay. Additionally, LED and mechanical flag indicators provide clear, immediate visual feedback on relay status, enhancing maintenance and operational monitoring.

This model incorporates a built-in bridge rectifier to seamlessly support both AC and DC coil voltages. The rectifier also suppresses back electromotive force (EMF), which can protect sensitive electronic components during DC operation. The coil power rating is designed for energy efficiency at 2.2 watts, while the coil resistance is 443 ohms.

Built to endure challenging environments, it operates reliably within a temperature range of -40°C to 60°C. The relay features durable silver alloy contacts specifically silver-nickel with a 10-micron gold layer, which provide excellent conductivity and corrosion resistance to ensure long service life. Through-hole terminal mounting offers a secure and stable connection directly onto printed circuit boards (PCBs).

This relay meets multiple international standards and approvals including EN, CSA, IEC, RoHS, and UL, assuring compliance and quality assurance for professional applications. The relay’s contact configuration is 3PDT for multi-circuit control.

Coil voltage is 24V AC/DC, suitable for diverse power sources. Switching current capacity of 10A supports moderate load demands. Operating temperature range from -40°C to 60°C for reliable use in harsh conditions. Coil power consumption of 2.2W optimizes energy usage.

Contact material silver alloy with silver-nickel and gold plating offers durability. Through hole terminals ensure secure PCB mounting and connection. Coil to contact isolation rated at 2.5kV enhances safety. Standards compliance with EN, CSA, IEC, RoHS, UL certifies quality.

Commonly used in industrial automation, electronic control panels, HVAC systems, manufacturing equipment, and other commercial applications where reliable power switching is critical. Compatible with PCB installations requiring high switching current and versatile contact arrangements.
